Problems solved by technology

In addition, due to the low content of N, P and other elements in the wastewater, the activated sludge cannot continuously obtain nutritional energy, and eventually loses activity or dies gradually, resulting in the paralysis of the entire biological treatment process
In the original wastewater treatment process, because the activated sludge basically died or the activity disappeared, the content of benzoquinones in the wastewater was always high. Therefore, the original whole set of processes could no longer effectively and stably degrade the phenol in the wastewater. Phenol, BOD and other indicators are high and extremely unstable, and sometimes even fail to meet the national sewage three-level discharge standard, which is not conducive to the long-term development of biopharmaceutical companies
[0004] At present, there are relatively few research reports on how to eliminate or reduce benzoquinone in industrial wastewater, and how to efficiently remove benzoquinone has become a technical problem in the treatment of industrial wastewater (especially wastewater from biopharmaceutical enterprises)

Abstract

The invention discloses a composite chemical for degrading pollutant benzoquinone in wastewater. The composite chemical consists of a stabilizer A, a microorganism energy supply material B and a flocculating agent C, wherein the mass ratio of mixing the stabilizer A to the microorganism energy supply material B to the flocculating agent C is (20-35) to (465-480) to (300-500). The method for degrading pollutant benzoquinone in wastewater with the composite chemical comprises the following steps: regulating pH value of wastewater; then, adding microorganism energy supply material B and flocculating agent C in the composite chemical to the wastewater, uniformly mixing, and adding stabilizer A in the composite chemical to the wastewater, wherein the adding concentration of the composite chemical is controlled to be not less than 120mg / L; reacting fully after mixing, and carrying out microorganism treatment so as to degrade the pollutant benzoquinone. The composite chemical disclosed by the invention has a good benzoquinone degradation effect and is stable, and is low in treatment cost and easy in implementation.

Description

technical field [0001] The invention belongs to the technical field of benzoquinone removal in industrial waste water, in particular to a benzoquinone degradation agent and a method for effectively removing benzoquinone by-product in industrial waste water. Background technique [0002] With the development of environmentally friendly industries, the trend of industrial systems to use water resources is to recycle production wastewater through further advanced treatment to reduce environmental pollution caused by sewage discharge. [0003] Phenol plays an important role in cracking BCG and extracting polysaccharide nucleic acid substances. It is one of the important raw materials for the production of BCG polysaccharide nucleic acid injection, but it is also one of the main by-products of the production workshop. For this type of phenol-containing industry For wastewater, some biopharmaceutical companies use chemical-biological activated sludge method to degrade phenols. Af...
